Samsung Galaxy Note 4 Browser Question

Do I lose any functionality in either of the 2 pre-installed browsers? I like the stock browser better than Chrome as it seems a little "lighter", has back and fwd arrows and allows me to auto scroll with the s pen. Chrome on the other hand always asks me to login to a Google account just to use the browser, which I find somewhat intrusive, and while it appears to have a few more bells and whistles, I just don't like it as much as the stock browser.

Is there any perceivable/substantive difference in the two? For that matter, are there better browsers out there? I previously tried Dolphin on my iPhone and it worked ok, but I always just stuck with Safari.
